Choyamba, voteji mu dera ndi okwera kwambiri, zomwe zimabweretsa kuwonongeka kwa ma capacitor a filimu.

Gawo lofunika kwambiri la capacitor ya filimu ndi voliyumu yogwira ntchito.Ngati voteji pa dera ndi kutali oveteredwa ntchito voteji wa capacitor filimu, pansi pa zochita za mkulu voteji, amphamvu tsankho kumaliseche ndi dielectric kuwonongeka zidzachitika mkati capacitor filimu, ngakhale kutsogolera ku kuwonongeka kwa capacitor.

Kachiwiri, kutentha ndi kokwera kwambiri.

Ma capacitor amakanema onse ali ndi kutentha kwawo komwe kumayendera.

Ma capacitor ambiri opangidwa ndi CRE amakhala ndi kutentha kwambiri kwa 105 ℃.Ngati filimu ya capacitor ikugwiritsidwa ntchito pa kutentha kwapamwamba kuposa momwe imaloledwa kwa nthawi yaitali, idzafulumizitsa kukalamba kwa kutentha kwa capacitor ndipo moyo udzakhala wamfupi kwambiri.Komano, pakuyika ndi kugwiritsa ntchito ma capacitors, chidwi chapadera chiyenera kuperekedwa kwa mpweya wabwino, kutentha kwa kutentha, ndi ma radiation pansi pa zochitika zenizeni zogwirira ntchito, kotero kuti kutentha komwe kumapangidwa mu ntchito ya capacitors kungathe kutayika panthawi, yomwe imatha kutalikitsa moyo wautumiki wa ma capacitor amafilimu.

Pomaliza, kugula ma capacitor amakanema osawoneka bwino.

Tsopano makampaniwa akusokoneza kwambiri, chifukwa msika ukusewera nkhondo yamtengo wapatali.Opanga ena, kuti ma capacitor awo akhale opikisana pamtengo, amasankha kugwiritsa ntchito ma capacitor otsika kuti ayese kukhala okwera, zomwe zingayambitse vuto loti kupirira kwenikweni kwa capacitor sikokwanira, komanso kosavuta kukhala nako. filimu capacitor ikuthyoledwa chifukwa champhamvu kwambiri.
